How to Apply for Volunteer Advisor – Data Engineer for Climate Tech & Open Data

at Climate Accountability API

🏢 About Climate Accountability API

Climate Accountability API is building open data infrastructure for ESG and climate-related information, a critical mission as companies face increasing pressure to disclose environmental impacts. This volunteer role offers a unique opportunity to shape the data pipelines that power transparency and accountability in corporate climate action.

About This Role

As a Volunteer Advisor, you will provide strategic guidance on data architecture, ingestion, and quality for ESG data from diverse sources like corporate filings and open datasets. Your expertise will directly impact the reliability and scalability of the platform, enabling better climate accountability.

💡 A Day in the Life

You might start by reviewing a proposed data pipeline design from the team, then provide feedback on schema normalization for a new ESG metric. Later, you could join a call to discuss trade-offs between using a document store vs. relational DB for provenance data, and end by documenting recommendations for data validation rules.
